Our kitchen faucet has leaked since installation. 2 yrs later and about $300 in plumbing bills and it is leaking so badly that we keep a towel wrapped around it. Price Pfister has repeatedly told us that instructions were in the mail as to how to repair the "new" faucet. The original plumber that installed the sink & faucet must have destroyed the receipt, so the store we purchased it from will do nothing. Any advise other than DO NOT BUY FROM PRICE PFISTER?
